Using the James Webb Space Telescope , astronomers have found the most distant merger between supermassive black holes ever detected. are at the heart of merging galaxies that are so distant that the collision is seen as it was happening just 740 million years after the, which are found at the heart of most large galaxies, have been responsible for driving cosmic evolution.
"Our findings suggest that merging is an important route through which black holes can rapidly grow, even at cosmic dawn," research leader and University of Cambridge scientist Hannah Übler."Together with other Webb findings of active, massive black holes in the distant universe, our results also show that massive black holes have been shaping the evolution of galaxies from the very beginning.
The team determined that one of the supermassive black holes involved in this merger had a mass equivalent to around 50 million suns. While they suspect that the second supermassive black hole has a similar mass, the scientists couldn't conclusively confirm this because of dense gas surrounding it.," team member Pablo G. Pérez-González, a scientist from the Centro de Astrobiología , said.
"The JWST's results are telling us that lighter systems detectable by LISA should be far more frequent than previously assumed," the ESA's Lead Project Scientist for LISA, Nora Luetzgendorf, said. "It will most likely make us adjust our models for LISA rates in this mass range. This is just the tip of the iceberg."early supermassive black holes.
